"Japan imported kanji some time during the first millennium to use as a writing system, despite there being no linguistic link between Japanese and Chinese. By around the eighth to ninth centuries, it had developed the hiragana syllabary, a system of consonant and vowel blends...Modern-day Japanese is a mixture of kanji, hiragana and katakana, with an increasing amount of Western script also thrown in, known as romaji, or Roman letters."
